Answer 1

You say that your Google Chrome installation was performed via the Programs package-management provider, rather than via the msi provider (for the latter, see the bottom section).

Assuming that $_.Meta.Attributes["UninstallString"] has a value, it contains a string that contains a no-shell / for-cmd.exe command line, which often will not work when executed directly from PowerShell with Invoke-Expression, because PowerShell has more metacharacters than cmd.exe that require quoting, notably { and }, as used in GUIDs.

• More fundamentally, &, the call operator does not support executing whole command lines, it expects only the name or path of a command or executable, optionally followed by arguments.

In the simplest case, you can do the following:

Get-Package 'Google Chrome' | % { 
  cmd /c ($_.Meta.Attributes['UninstallString'] + ' /S')
}

IF your Google Chrome was installed via the msi package provider (verify with: (Get-Package 'Google Chrome').ProviderName):

Not all installed programs have an UninstallString attribute (and even fewer have a QuietUninstallString one), and an msi-provider-installed Google Chrome doesn't have one.

However, you should be able to pipe to Uninstall-Package for silent (unattended) uninstallation:

Get-Package 'Google Chrome' | Uninstall-Package
